Doctoral thesis: Elucidating Chemical and Electrochemical Side-Reaction Mechanisms in Li-ion Batteries

Neeha Gogoi Uppsala University, Department of Chemistry - Ångström Laboratory, Structural Chemistry, defends her thesis Elucidating Chemical and Electrochemical Side-Reaction Mechanisms in Li-ion Batteries

Lithium-ion batteries constitute a leading technology that plays a major role in the transition towards sustainable transportation and power generation. The stability of modern batteries relies on a passivation layer formed on the negative electrode known as the solid electrolyte interphase (SEI). Despite concerted efforts to comprehend the various processes taking place during SEI formation, monitoring the reaction pathways in real-time is still very challenging. This is due to the complex interactions within the multicomponent electrochemical system, aggravated by the wide range of electrolyte compositions, electrode materials, and operating conditions.

The thesis contributes to a deeper fundamental understanding of the myriad of processes that take place in batteries during SEI formation providing insights crucial for designing next-generation battery materials.
